“Bought three new swimsuits today,” she captioned the selfies. “This one is my favorite!”

In the photos the mother of two shows off her hourglass shape in the racy suit, with string cutouts all up the sides.

It certainly isn’t the first time Brit has dared to bare. Despite accusations of Photoshop, the “Pretty Girls” singer has regularly posted bikini pics. In March she shared a shot by the pool and then on a trip to Hawaii she flashed her impressive abs in a blue two-piece in the ocean.

In addition to keeping fit, Britney is also preparing to accept the Millennium Award at the Billboard Music Awards later this month. The chart-topper will perform a medley of her hits to honor the occasion. Past recipients of the award include the late Whitney Houston and Beyonce.
